Description

DETAILED DESCRIPTION OF THE INVENTION (Field to which the invention pertains) The present invention relates to a character size designation device that allows characters of various sizes to be displayed on a character display device etc. to be input easily and efficiently with simple operations. It is something.

(Prior art) In order to display characters of various sizes on the display screen, conventional devices have a configuration in which keys are pressed according to the size of each character when inputting. The disadvantage is that the operation for specifying the size is complicated, and the number of specifying keys must be increased as the character size increases.

(Objective of the Invention) In order to solve these drawbacks, the present invention changes the font size with one key, and by continuously pressing the corresponding key, multiple font sizes can be sequentially changed according to the number of presses. In addition to simplifying the specification and operation, it also counts the frequency of use of characters of each size and allows you to select the most frequently used size with fewer key presses, making the operation more efficient. Explain.

(Structure and operation of the invention) FIG. 1 is a block diagram of an embodiment showing the structure of the present invention, in which 1 is a keyboard, 2 is a character code generation section, 3 is a bus, 4 is a central processing section, and 5 is a block diagram of an embodiment of the present invention. A character size control section, 6 a cursor control section, 7 a display control section, 8 a display section, and 9 a character font generation section.

The operation will be explained below. First, when a character size designation key (not shown) on the keyboard 1 is pressed, a notification is sent to the central processing unit 4 via the character code generation unit 2 and the bus 3. The central processing unit 4 is
The font size is determined by receiving from the font size control unit 5 information on the frequency of use according to the number of times the size specification key is specified, and the font size is notified to the character code generation unit 2. At the same time, the cursor control unit 6 controls the display. unit 7 to display a cursor of the determined size on display unit 8. Thereafter, characters inputted from the keyboard 1 are converted by the character code generating section 2 into character codes of a size notified in advance. The central processing section 4 controls the display control section 7 and the character font generation section 9 to display the corresponding character in the specified size on the display section 8, and at the same time updates the usage frequency counter of the character size in the character size control section 5.

FIG. 2 is a diagram showing details of the character code generation section 2 and character size control section 5 shown in FIG.

In the character code generation section 2, 21 is an interface circuit, 22 is a code conversion circuit that converts a code from the keyboard into an internal code, 23 is a status register that temporarily stores the internal code, and 24
25 is a designated number of times register that stores the number of presses of the size designated key, and 25 is a size register that stores the code of the determined size. Further, in the character size control section 5, 51 is a size counter control circuit that controls a size counter according to the number of times a character of each size is used, and 52 is a size counter that stores the number of times each character size is used.

When a character size designation key (not shown) is continuously pressed to change the character size using the keyboard 1, the signal is converted by the code conversion circuit 22 via the interface circuit 21, and is input to the status register 23. At the same time, the number of presses of the character size designation key is stored in the designation number register 24. The contents of the status register 23 are input to the central processing unit 4 via the bus 3, where it is determined whether it is a character code or a function code.If it is a function code with a specified size, the contents of the specified number of times register 24 are inputted to the central processing unit 4 via the bus 3. and the number of uses of each character size stored in the size counter 52 read through the size counter control circuit 51 are determined, and characters with a frequency of use according to the number of times the character size designation key is pressed in succession are determined. The size identification code is input into the size register 25.

A code conversion circuit 22 of the character code generating section 2 converts the character code inputted via the keyboard 1 and the interface circuit 21 into a character code of a corresponding size according to the size register 25. The converted code is input to the status register 23, determined to be a character code by the central processing section 4, and displayed on the display section 8 by controlling the display control section 7 and character font generation section 9. At the same time, the size counter 52 is controlled via the size counter control circuit 51.
Add 1 to the counter of the corresponding size.

Therefore, when the font size change key is pressed once on the keyboard, the font size is changed to the most frequently used font size at that time, and the font size is changed continuously 2, 3, etc.
If you press the button twice, the second, third, etc. most frequently used size will be selected.

(Effects) As explained above, in the present invention, the desired size can be selected with a single operation such as pressing the font size change key, and frequently used sizes can be selected with a small number of presses. Since it is structured so that the appropriate size can be selected, the font size can be changed efficiently with simple operations, which has the advantage of shortening input time.
